Lessons for 10/17

Course 2: Multiply Fractions

Remember you do NOT need common denominators for this!
You just simply multiply across, then simplify.

Here's a video from the lesson 7th hour...enjoy!


Pre-Algebra: Adding and Subtracting Fractions

You MUST have common denominators. I like the "spelling book" method; this was learned in 6th grade.
You then just add or subtract the numerators and simplify.

Here's a video of our lesson in class; this was the first one I'd ever done this way. It's very hard to hear the class, however it still shows our entire lesson (and you can hear my wonderful voice!) :)
